IMPROVEMENT IN WASH-BOILERS.

TO ALL WHOM IT MAY OONCERN:

Be it known that I, JAY C. MERRELL, of Medina, in the State of New York, have invented a ncwand useful Improved Clothes-Boiler; and I do hereby declare that the following is afull, clear, Aand-exact description thereof, reference being had to the accompanying drawing, making part of this specification. I

My invention consists in certain improvements in the ordinary clothes-boilers used on stoves, whereby the same is so arranged that it may be used on the stove in the ordinary manner, and can also be used independently ofthe stove, for the purpose of boiling clothes, heating water, dre.

In the accompanying drawings- Figure 1 is a longitudinal vertical section of my improved boiler, arranged for use senarate from the stove.

Figure 2 is a transverse vertical section o f my improved boiler, and

Figure Sis an end view of the same.

In constructing my improvements I take an ordinary clothes-boilerand Vinsertthrough it, longitudinally,

near the bottom, a tube,`l3, open at each end, and soldered or otherwise secureduto the boiler at cach end, rse as to be water-tight. Over thistube, -within the boiler, I locate a perforated plate, o, as shown more clearly in iig. '2, this plate o being arranged to rest loosely on ledges or liauges, vso that it may be'removed when notrequired for use. At each end of the boiler I locate a slide, C, as shown in figs. l and 3, of proper size to close the ends of the tube B when the boiler is to be used on the stove in the ordinary manner.

I`tl1eu provide a small grate, I, of proper size and form to rit Within the lower part of the tube B, as shown in iig. 1. 'lhis grate having a right-angled plate, a d, at its front end, and a vertical plate, q, at its rear end; the plate a serving to prevent the air which enters below from passing upward between it and the slide C, andf causing it to pass backward under and up through between the bars of the grate'F; the plate q serving to close the space underneath the rear end ofthe grate, and causing the flame and hcat to rise and pass over it. I also propose to use one or more. vertical plates H, provided withY suitable base or legs to hold them in position, as represented in iig. 1, to serve as delectors to break` the direct current of thcltlame and heat, and thus arrest and retain the heat longer in the tube B.

I -then provide a short tube, D, of proper size to t snugly within one end ofthe tube B, said tubs having its outer end elosed,'and being provided with a vertical tube, P, to serve as a chimney and create a draught, and convey away the smoke. If desired, a cock, m, `may be attached to the boiler to draw oil' the water, as shown in lig. 3. i

'lhe operation is as follows: When the boiler is used in the ordinary way on the stove, the plate o, with the tube D, and the grate and iixtures, are-allremoved, and the slides G closed, to retain the heat, and prevent it 4from escaping at the open ends of the tube B. vThus arranged, it is used the same'as the ordinary boiler.

When, however, it is desired to use it separate from the stove,tl1e tube B is attached, and the grate inserted, as shown in iig. 1, and a lire is then kindled on the grate within the tube B, the slide C, at the front end ofthe grate, heilig opened sufliciently to give the proper draught to the re. The fire beingthus surrounded by the water in the boiler on all sides, except at theA ends, is applied in a very efficient manner, and a small amount of -f'uel made to answer the purpose. By these means the boiler may be used independent of .the stove, and the necessity for a het fire in the latter entirely obviated,wliicl1 in warm weather is a great object. When the boiler is thus used, it may be located out of doors, or in any out-building; and when thus located, charcoal may be used for heating it, without the deleterious effects that would arisei'rom its use in the house.' When thus used, the boiler may be set on the floor, or on a bench or table, as the water below-the tube B will prevent any danger from fire. It may be desirable, espceiallyvif used out el' doors, to surround the boiler with a sheet-iron orother metallic euse, as represented by L in iig-.,I, to prevent a loss ofthe heat by radiation, or a cooling of the boiler and its contents by cold currentsI of air. v

ly this improvcmentthe boiler may be used as an independent or iauxiliary furnace, for boiling clothes,

heating water, or any similar `purpose, thus leaving the whole of the stove to he occupied lfor other purposes; and this, especially with farmers and others living in the country, is oftentimes very desirable.

Having thus (lesoribed my invention, what I claim,'is-

The hoivler A, provided with the tubeB and slides C, and having tire auxiliary tube D and Kgrate I nrrnnged n for use in connection therewith, for the purpose of adapting the boiler to use either with or independent of the stove, substantially as described.

JAY C. MERRELL.
